Brief Summary

To investigate the effect of three single oral doses of BIA 9-1067 (25 mg, 50 mg and 100 mg) on the levodopa pharmacokinetics when administered in combination with a single-dose of controlled-release levodopa/carbidopa 100/25 mg (Sinemet® CR 100/25)

Detailed Description

Single centre, double-blind, randomized, placebo-controlled, crossover study with four consecutive single-dose treatment periods. The washout period between doses was to be at least 14 days. On each treatment period, after completion of pre-dose assessments, BIA 9-1067/Placebo was to be administered concomitantly with the dose of Sinemet® CR 100/25; post-dose assessments were to be completed and subjects were to be discharged 72 h post-dose. Subjects were to attend four treatment periods and were to receive a different dose of BIA 9-1067 (25 mg, 50 mg and 100 mg) or placebo during each of these treatment periods.

• Volunteers who took an Investigational Product (in another clinical trial) or donated 50 mL or more of blood in the previous 28 days before day 1 of this study.
• Poor motivation, intellectual problems likely to limit the validity of consent to participate in the study or limit the ability to comply with the protocol requirements or inability to cooperate adequately, inability to understand and to observe the instructions of the physician.
• Donation of 500 mL or more of blood (Canadian Blood Services, Hema-Quebec, clinical studies, etc.) in the previous 56 days before day 1 of this study.
• Positive urine screening of ethyl alcohol or drugs of abuse at admission to any treatment period.
• Any history of tuberculosis and/or prophylaxis for tuberculosis.
